Uma kuziwa ekubumbeni uhlelo olukhulu lwezemidlalo yaseshashalazini, i- subwoofer iyodingeka ukuthenga . I-subwoofer iyisipikha esikhethekile esenzelwe ukukhiqiza ama frequencies aphansi kakhulu. Ngomculo, lokho kusho ukuthi isisekelo somsakazo noma ogesi, kanye nama-movie angaphezulu okusho ukuqhuma kwesitimela egijima ngaphansi kwamathrekhi wesitimela, umgogodla umlilo kanye nokuqhuma, nokuhlolwa okukhulu: ukuzamazama okukhulu kokuzamazama komhlaba.
Kodwa-ke, ngaphambi kokuba ujabulele konke, kufanele uhlanganise i-subwoofer neyonke uhlelo lwakho, nokuthi uxhumana kanjani ne-subwoofer kukho konke okusetha ukusetha kwethempeli lakho ukuthi kuncike ekutheni ngabe ku-Passive noma kunikwe amandla.
I-Subwoofers engamaphutha
Ama-subwoofers amancane abizwa ngokuthi "awunamatheli" ngoba adinga ukunikezwa amandla okukhulisa ngaphandle, ngendlela efanayo namazwibela wendabuko. Okubalulekile okucatshangayo lapha ukuthi njengoba ama-subwoofers adinga amandla amaningi okukhiqiza imisindo ye-frequency ephansi, isikhulumi sakho noma umamukeli kumele akwazi ukukhipha amandla anele ukusekela imiphumela ye-bass eyakhiwe yi-subwoofer ngaphandle kokukhipha ukunikezwa kwamandla ku-receiver noma amplifier yakho. Amandla angakanani ancike ezimfuno zesitatimende se-subwoofer nobukhulu bekamelo (nokuthi zingaki ezingezansi ongakwazi ukuzenza ngesisu, noma ukuthi ufuna ukuphazamisa omakhelwane kangakanani!).
Njengoba nje wonke ama-loudspeakers esethulweni sendawo yendabuko yasendlini, uxhuma ucingo lwesipikha kusuka kwesikhulumi se-subwoofer engavamile. Okufanelekile, kufanele uqale ukuxhuma imiphumela yomugqa we- subwoofer we-receiver yemidlalo yaseshashalazini noma iprojector ye-AV preamp , emigomeni yemigqa ye-amplifier yangaphandle ye-subwoofer - bese uxhuma i-subwoofer engenazikhala kumasekhondi esikhulumi anikezwe ku-amplifier ye-subwoofer.
Isibonelo esisodwa se-Passive Subwoofer yi-OSD Audio IWS-88 In-Wall Subwoofer.
Isibonelo esisodwa se-amplifier yangaphandle esidingekayo uma usebenzisa i-Passive Subwoofer yi-Dayton Audio SA230.
Ama-subwoofers angasetshenziswa ngokuyinhloko ekufakweni okungokwezifiso lapho i-subwoofer ingase ifakwe eludongeni, nakuba kunamanye ama-subwoofer afana ne-cube afana nawo. Futhi, amanye ama-home-a-box-in-box-systems angabizi kakhulu afaka i-subwoofer engavamile, njenge- Onkyo HT-S3800 .
I-Subwoofers enikwe amandla
Ukuxazulula inkinga yamandla angenele noma ezinye izici ezihlobene ezingase zingekho kumamukeli noma amplifier, i-Powered Subwoofers (ebizwa nangokuthi i-Subwoofers esebenzayo) isetshenziswa. Lolu hlobo lwe-subwoofer luyisimo sesikhulumi / isikhulumi esizimele esizimele lapho izici ze-amplifier ne-subwoofer zifaniswa kahle futhi zombili zifakwe endaweni efanayo.
Njengenzuzo ehlangothini, zonke izidingo ze-subwoofer enezinkampani ezixhasiwe yi-cable eyodwa yokuxhumeka kwi-home receiver noma umkhiqizo we-preamp / umshini wokucubungula umsindo (okukhulunywa ngawo njengomkhiqizo we-prewoofer preamp noma ukukhiqizwa kwe-LFE). Leli lungiselelo lithatha umthwalo omkhulu wamandla kude nomuntu owemukelayo futhi ivumela abanikeli bamakhompiyutha ukuba bakwazi ukulawula amandla okukhulumisana phakathi kwezigaba kanye nezikhulumi ze-tweeter kalula.
Esinye isibonelo se-Powered Subwoofer yi- Fluance DB150 .
Yikuphi okungcono - i-Passive noma i-Powered?
Zonke ezinye izinto zilingana, kungakhathaliseki ukuthi i-subwoofer ayihambisani noma inikwe amandla ayiyona into ecacisa ukuthi i-subwoofer ihle kangakanani. Kodwa-ke, ama-subwoofers Amandla asebenzayo asetshenziswa kakhulu njengoba anama-amplifiers akhe awakhiwe futhi awaxhomeki kunoma yikuphi ukulinganiselwa kwe-amplifier komunye umamukeli noma amplifier. Lokhu kwenza kube lula kakhulu ukusebenzisa nalabo abamukelayo yaseshashalazini namuhla. Bonke abamukelayo yaseshashalazini basekhaya bahlonywa ngemiphumela eyodwa noma emibili ye-subwoofer yangaphambi kwe-amp line eyenzelwe ngokuqondile ukuxhuma ku-subwoofer ene-powered.
Ngakolunye uhlangothi, lokho okudingeka ukwenze ukuze usebenzise i-subwoofer engenamathengi ukuthenga i-subwoofer amplifier ezinikezele, okuyinto, ezimweni eziningi ingaba kubi kakhulu kune-subwoofer engenayo.
Ngamanye amazwi, ezimweni eziningi kungaba yimali engcono kakhulu ukuthenga i-subwoofer ene-powered esikhundleni se-Passive Subwoofer. Uma ukhetha le nketho i-subwoofer ephuma ngaphambi kwe-Receiver Home Theater yayizoxhumeka kumzila wangaphandle we-ampwofier wesikhulumi-ekuxhumekeni, uxhumano lwe-subwoofer lwesikhulumi sangaphandle lwama-amplifier oluya ekuxhumeni kwesipikha ku-subwoofer engavamile.
Okunye okunye okukhethwa kukho kokuxhuma yilokho okutholakala nge-subwoofer engavamile yukuthi uma i-subwoofer engenawo ngaphakathi inexhumano lesikhulumi esiphezulu nongaphandle, ungaxhuma uxhumano lwesipikha kwesokunxele nesokudla kumamukeli noma amplifier ku-subwoofer engenayo bese uxhuma kwesokunxele kanye nokukhulumisana kwesokudla kwesiphakamiso esivela ku-subwoofer engenayo kuya ezikhulwini zakho zangakwesokunxele nezilungile ngakwesokudla (bona isithombe).
Okwenzekayo kulokhu kusetha ukuthi i-subwoofer "izokhipha" ama-frequencies aphansi esebenzisa i-crossover yangaphakathi, eyathumela ububanzi obuphakathi nendawo ephezulu kumazwi athile engeziwe ezixhunyaniswe neziphakamiso zesiphakamiso se-subwoofer.
Lolu hlobo lokusetha luzoqeda isidingo sokukhulisa ngaphandle kwe-amplifier ngaphandle kwe-subwoofer engavamile, kodwa kungafaka umshini omkhulu kumemukeli noma amplifier ngenxa yezimfuneko zokukhishwa kwezwi eliphansi lemvamisa.
I-Exceptions kuya emithethweni yokuxhumeka kwe-Subwoofer
Kubalulekile ukuqaphela ukuthi amanethiwekhi amaningi angaphansi kokufakelwa komugqa kanye nokuxhumana kwezikhulumi. Uma kunjalo, i-subwoofer yi-Powered Subwoofer. Noma kunjalo, kulesi sibonelo, i-subwoofer engakwazi ukwamukela izibonakaliso kusuka kokuxhumeka kwesipikha se-amplifier noma ukuxhumeka kokukhipha ukukhishwa kwe-pre-emergency receiver.
Lokhu kusho ukuthi uma une-receiver yasekhaya endala noma i-amplifier engenawo uxhumano lokukhishwa kwesibonakaliso se-subwoofer esinikeziwe, usengasebenzisa i-subwoofer ene-powered, uma inikeza ukuxhumeka kwesipikha okujwayelekile ngaphezu kokungeniswa komugqa. Kudinga ukubekezela okuncane kodwa akulona kunzima ukuxhuma .
I-Option Wireless Connection
Futhi, enye inketho yokuxhumeka kwe-subwoofer etholakala kakhulu (isebenza kuphela ngama-subwoofers anikwe amandla) ukuxhuma okungenantambo phakathi kwe-subwoofer ne-receiver yasekhaya noma i-amplifier. Lokhu kungaqaliswa ngezindlela ezimbili.
Enye indlela lapho i-subwoofer ifika ngesamukeli esingaxhunyiwe engenantambo futhi inikeza umthumeli wangaphandle ongenawo ucingo ophuma emgqeni we-subwoofer owamukelayo we-home or amplifier.
Isibonelo esisodwa se-Wireless Subwoofer yiyona ndlela engabizi kakhulu ye-Monoprice 110544 8-inch 110-watt model.
Inketho yesibili ukuthenga ithikithi le-wireless / i-receiver elingenayo i-wireless elingakwazi ukuxhumeka kunoma iyiphi i-subwoofer ene-powered ene-line input kanye nanoma yisiphi isamukeli semidlalo yaseshashalazini, i-processor ye-AV, noma i-amplifier ene-subwoofer noma i-LFE yokukhishwa komugqa.
Isibonelo esisodwa sekithi ye-Wireless Subwoofer Transmitter / Receiver yi-Sunfire Wireless Subwoofer Connection Kit.
Thatha okokugcina
Uma uthenga i-subwoofer ukuyisebenzisa ngeshashalazi yakho yasendlini, hlola ukuze ubone ukuthi indawo yakho yaseshashalazini yasekhaya, i-AV, noma isamukeli somsindo ozungezile inomkhiqizo we-prewo Outer, ngokuvamile obizwa nge-Sub Pre-Out, i-Sub Out, noma i-LFE Out). Uma kunjalo, kufanele usebenzise i-subwoofer ene-powered.
Futhi, uma usanda kuthenga isamukeli esisha sendawo yaseshashalazini, futhi ube ne-subwoofer engakwesokunxele eyayiqala nge-home-in-a-box box system, hlola ukuze ubone ukuthi leyo subwoofer empeleni iyisimo se-subwoofer engenziwanga. I-giveaway yukuthi ayinayo i-subwoofer line input futhi inexhumano lesikhulumi kuphela.
Uma kunjalo, kuyodingeka uthenge noma umkhuliseli owengeziwe ukuze usebenzise i-subwoofer, noma, uma i-subwoofer inokufaka kokubili kwesikhulumi kanye nokuxhumeka kwesipikha sesipikha, ungakwazi ukuxhuma i-subwoofer kwiziphumo eziphambili zesipikha sesokunxele / kwesokudla we-receiver bese uxhuma izikhulumi zakho ezisemuva nezakwesokudla ekuphumeni kwesipikha se-subwoofer engenziwanga.
Kusuka endlini engabizi-yaseshashalazini-in-a-box kuya ohlelweni oluphezulu oluhlelekile lwezinhlelo ezifakiwe, i-subwoofer iyadingeka ukuze inikeze lezo zikhathi eziphansi ze-bass.
